Description

Technical Field

[0001] This utility model relates to the field of PCB board testing technology, specifically to a PCB board warping measurement tool. Background Technology

[0002] As electronic products continue to develop towards multifunctionality and high performance, the requirements for PCB boards are becoming increasingly stringent, and the price of high-grade materials is also rising. In order to save costs and meet performance requirements, several different materials have been mixed-pressed laminates. However, mixed-pressing laminates bring new problems. Due to the inconsistent shrinkage of different materials, PCB boards may warp.

[0003] Currently, there are board warping inspection machines for finished PCB boards and copper-clad laminates. However, during the PCB product development and testing stage, some boards with severe warping still need to be manually measured for warping. Manual measurement is generally done using pin gauges and feeler gauges. Pin gauges and feeler gauges come in various specifications, and each one needs to be selected and combined during measurement, resulting in low data collection efficiency. Furthermore, it is very troublesome to wipe the pin gauges and feeler gauges clean, apply anti-corrosion oil, and store them properly after use. Utility Model Content

[0004] The purpose of this invention is to provide a PCB board warping measurement tool to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB board warping measurement tool, comprising:

[0006] The measuring tool is a right-angled triangular plate with a 10-degree angle between its long straight side and its hypotenuse. The long straight side of the measuring tool is provided with scale lines, and a support component is detachably installed at the hypotenuse of the measuring tool.

[0007] Preferably, the support assembly includes a first L-shaped support and a second L-shaped support, which are distributed on both sides of the measuring instrument. The bottom of the first L-shaped support and the second L-shaped support match the bottom inclined edge of the measuring instrument. The first L-shaped support and the second L-shaped support are snapped together. The first L-shaped support and the second L-shaped support support the measuring instrument so that the measuring instrument can stand upright.

[0008] Preferably, the vertical plate of the first L-shaped support has multiple locking blocks fixed on the side near the measuring tool, and the vertical plate of the second L-shaped support has multiple locking slots. The locking blocks pass through the measuring tool and engage with the locking slots, making the connection between the first L-shaped support and the second L-shaped support simple and quick, and also easy to disassemble.

[0009] Preferably, the first L-shaped support and the second L-shaped support are made of PVC material, which makes the first L-shaped support and the second L-shaped support have high strength and high toughness, and are easy to process and form, with low manufacturing cost.

[0010] Preferably, the measuring tool has through holes at the positions corresponding to the multiple locking blocks, and the locking blocks pass through the through holes to facilitate the connection between the first L-shaped support and the second L-shaped support.

[0011] Preferably, the measuring tool has a triangular groove, which saves materials and improves aesthetics.

[0012] Preferably, the measuring tool is made of PVC material, which gives it high strength and high toughness, and makes it easy to process and shape, resulting in low manufacturing cost.

[0013] Preferably, the measuring tool has a frosted portion on both sides near the short straight edge. The frosted portion increases the friction between the finger and the measuring tool, making it more stable to hold and less likely to slip and fall.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The measuring tool is a right triangle with an angle of 10°. It has scale lines on its long straight side. When measuring, the triangle is inserted into the warped area with the hypotenuse as the base. After insertion, the scale of the long straight side is read and recorded. The scale is multiplied by sin 10° to get the warped value. The operation is simple and convenient. Unlike feeler gauges and pin gauges, it does not require the use of different specifications for comparison. It can effectively increase the efficiency of data measurement.

[0016] 2. The measuring tool has a detachable support component at its beveled edge. The support component can support the measuring tool, allowing it to stand upright and preventing it from tilting during measurement. The support component is also easy and convenient to assemble and disassemble from the measuring tool. Attached Figure Description
